I enjoyed this movie, even the scenes in Zion. It showed that the people of Zion still retain much of their humanity, despite the machines that are trying to kill them nonstop, that they can take a break from constant duty and try to enjoy themselves. They have kinda crummy taste in music though, that techno-house crap is poo-poo. ;P
I liked the Merovingian alot too, he's hilarious. Also the Twins were badass, they will be back in the third film. All and all the last 40 minutes of the film were the best.
